NOAA cuts back on seismic data used for West Coast tsunami alerts

November 12, 2025 — The National Oceanic and Atmospheric Administration ended a contract with the Alaska Earthquake Center that helped maintain some seismic stations and transmit data in real time.

Alaska state seismologist and director of the center, Michael West, warned that the termination of this contract, which is around two decades old, will lead to less timely and accurate tsunami warnings that could affect Alaska, Hawaii and the West Coast.

It’s unclear why NOAA chose to terminate the contract, worth around $300,000 annually. David Snider, a tsunami warning coordinator with NOAA’s National Tsunami Warning Center, declined to comment, deferring to NOAA public affairs, which did not respond to request for comment.

Every time an earthquake happens, NOAA’s Tsunami Warning Centers determine whether to issue a tsunami alert within five minutes. Depending on where the earthquake originated, coastal communities could have anywhere from 20 minutes to six hours to evacuate or prepare for a tsunami.

Major quake hits off the coast of Alaska, triggers tsunami warnings but no large waves

July 30, 2021 — A major earthquake struck near the Alaska Peninsula at 10:15 p.m. Wednesday, triggering tsunami warnings for much of the Gulf of Alaska coastline, but no large waves.

The magnitude-8.2 quake hit roughly 60 miles offshore of the tiny community of Perryville, reported the U.S. Geological Survey.

“This is the largest earthquake to happen in the Alaska region since 1965,” said Michael West, state seismologist with the Alaska Earthquake Center.

There were no immediate reports of major injuries or damage, but officials said that could change as people get a better look over the next few days.

After the initial tsunami warnings late Wednesday, the National Tsunami Warning Center in Palmer said at midnight that the waves caused by the quake were likely to be smaller than a foot.
